CAR.

Specification of Letters Patent.

Patented Nov. 6, 1906.

Application filed August 1B, 1906' Serial No. 330,442,

To all whom it may concern;

Be it known that I, EDGAR WEBSTER SUM- MERS, of Wilkinsburg, in the county of Allegheny and State of Pennsylvania, have invented a certain new and useful Im rovement in Cars, of which improvement the following is a specification, reference being had to the accompanying drawings, forming part, of this specification, in which- Figure l is a vertical longitudinal section taken on line 1 1 in Fig. 3, the end portions of the car, from the bolster out, being broken away, showing only the inner wheels of the four-wheeled trucks. Fig. 2 is a plan View of the car, taken in line 2 2 in Fig. 1, the end sloping floor-plates being omitted in this view and the ends of the car broken away from the bolster out, the truck-wheels shown being the inner wheels of the ordinary fourwheeled truck. Fi 3 is a vertical crosssection of the car, ta en in line 3 3 in Fig. 1.

It is intended to use the standard equip ment-such as trucks, brake mechanism, &c.; but only such portions of this equipment are shown, as is needed to show the relation of such equipment to the new feature in this car.

My invention relates to that class of cars having drop-bottoms for dischargin the load and is intended more particular y for carrying and discharging iron oreand similar materials.

The conditions in the ore-handling trade re uire a car. much shorter than the ordinary rai way-car in order that a whole train of them may be placed so that each car will be located centrally over a pocket in-the oredocks, the spacing of the pockets being made to conform with the spacing of the hatch-' ways on the ore-carrying ships. On account of theshort length of the car the space (longitudinally of the car) between the inner truck-wheels is so small that the door-opening in this space has not been suflicient to prevent the ore bridging over the o ening. As an improvement over ,this con ition I have devised a drop-door construction which ermits of a larger clear openin in the botcm of the car than the space lietween the wheels, both longitudinally and transversely of the car.

In the drawings I show the side doors 1, the side-door hinges 2, the side-door-supporting beams 3, the door-supporting chains 4, the chain-winding shafts 5, the worm-Wheels 6. the worms 7, the worm-shaft 8, the

sprocket-wheel 9 on the worm-shaft, the sprocket-wheel 10 on the crank-shaft 11, t 1e crank 12,, the chain-pocket wheels 13, with their roller-supporting arm 14, the roller 15, which is pivotally connected to the roller-arms 14, the end doors 16, having their hinge-axis transversely of the car, the end-door hinges 17 the end-door-closing bracket 18, the end sloping floor 19, with its curved portions '20 at thesides of the car, the side sloping floor 21, the car sides 22, the draft-sills 23, the inner truck-wheels 24. It will be seen that the doors 1 and 16 extend both transversely and longitudinally beyond the. truck-wheels 24, leaving a clear opening in the car-bottom, which opening is wider than the car-tracks transversely of the car and longer longitudinally of the car than the space between theinner truck-wheels. The draft-sills 23 extend from the end of the car into the door-opening only, there being no center sills.

The side doors 1 are hinge-connected at the sides of the car and are supported near the center line of the car on the door-suporting beams 3, which beams extend beyond the doors 1 and are supportedly connected to the chains 4 and the winding shaft 5, which winding operation is operated through the Morm-gearing 6 and 7 by means of the shafting 8, the sprocket-wheels 9 and 10, and the crank 12. The sprocket-wheels 9 and 10 are connected by means of a chain belt, which for clearness of detail is omitted from the drawings. The doors 1 are shown in full lines in their closed position, and in Fig. 3 they are also shown by broken lines in an open position. The chains 4 ass over the pocket-Wheels 13. The links 0 the chain en gaging in the pockets of the wheel cause the wheel to rotate about its axis in the direction the chain is moving. In Fig. 1 the roller 15 is shown in contact with the end-door-closing bracket 18. By lowering the side doors 1 the chain 4 in passing over the wheel 13 causes the roller 15 to rotate downwardly and then toward the end of the car until the said roller reaches a position, as shown by dotted lines 25, which permits the end doors 16 to rotate about their hinge-axes 17, the door and bracket assumin the position as shown in dotted lines 26,. he reverse action of closing the side doors will also close the end doors, the whole door-operating mechanism being actuated when opening and closing by means ofthe one crank 12.

On account of the adhesive properties of iron ore and such materials I have made the end sloping floor-plate with a curved section at its juncture with the side plates. The end and side sloping floor-plates are made uite steep in order that the material may sli e oii into the door-opening. The door-opening is made large in order that the ore or other material may not bridge or arch itself over the opening.

Many changes may be made in the form and arrangement of the doors and in the details of actuating mechanism and in-the shape and arrangement of the car-body in general without departing from my invention.
